Length–weight relationships were estimated for the first time for seven species of gurnards (Triglidae) based on data collected over the past 27 years in the Adriatic Sea (northeast Mediterranean). Results show significantly different relationships between juveniles and adults (females and males combined) for Aspitrigla cuculus, Eutrigla gurnardus, Chelidonichthys lucerna and Lepidotrigla cavillone. Isometric growth of juveniles is indicated for four species, allometric growth of adults for all species.
